Abstract:
We experimentally investigate charge exchange of ions passing through
thin carbon foils of 1.1-10 mu gm cm-2 thinkness at incident
energies from 0.5 to 5 keV/u. At such low energies usually only the
charge exchange processes occurring at the back surface determine the
final charge state of the emerging projectiles. However, for some
elements we observe a significant foil thickness dependence which
cannot be explained by current models. Possible reasons for this
thickness dependence are discussed in this paper. We further present
new data on charge state yields for Mg, Ca, Ti, Cr, and Ni.
